.If a pipe can fill the tank within 6 hrs but due to leak it took 30 min more
now if the tank was full hw much tym will it take to get emptyed through the leak??(i dont remembr whole sum exactly)(lil bit tricky sum)

time taken to fill tank is 6hrs
thus amount of water pumpes is 1/6
let rate of empyting t, thn amt of water emptied per hour s 1/t
time taken to fill due to leak s 6.5 hr..
per hour amt is 1/6.5
thus we get
1/6 - 1/t = 1/6.5
thus t = 78 hours

Let the capacity of the tank be 6 liters then efficiency is 1 liter/hr.
If it took extra half an hour that means work done by leak in 6 hour and 30 minutes =work done by pipe in half hour.
So, it would be 12*6.5=78 hours
